Meeting Sexual Partners Through Internet Sites and Smartphone Apps in Australia: National Representative Study

Engaging older Australians in sexual health research: SHAPE2 survey recruitment and sample

BACKGROUND

Sexual health research rarely includes older age groups and the sexual health needs of older Australians are not well understood. Older adults are online in increasing numbers; however, internet surveys involving samples of older adults and sensitive topics remain uncommon. In 2021, we developed an online survey to explore the sexual health needs of Australians aged 60+years. We describe here survey recruitment and sample obtained, comparing it with national population data (Australian Bureau of Statistics) and the sample of the similar 'Sex, Age and Me' study from 2015.

METHODS

We recruited 1470 people with a staggered three-phase strategy: (1) emails to organisations and community groups; (2) paid Facebook advertising; and (3) passive recruitment. Half (50.6%) found out about the study via an organisation or group and just over a third (35.7%) from Facebook.

RESULTS

The sample was equally balanced between men (49.9%) and women (49.7%) (0.4% other gender identities). Participants were aged 60-92years (median 69years) with all Australian States/Territories represented. Facebook recruits were younger, more likely to be working rather than retired, and more likely to live outside a major city, than those recruited by other means.

CONCLUSIONS

Using the recruitment methods described, we successfully obtained a diverse and fairly representative sample of older Australians within the constraints of a convenience sample and on a modest budget. This research sheds light on ways to engage an under-served demographic in sexual health research. Our experience shows that many older adults are amenable to recruitment for online sexual health surveys using the approaches outlined.

The Role and Impact of Artificial Intelligence in Addressing Sexually Transmitted Infections, Nonvenereal Genital Diseases, Sexual Health, and Wellness

The potential of artificial intelligence (AI) in diagnosing and managing sexually transmitted infections (STIs), nonvenereal genital diseases, and overall sexual health is immense. AI shows promise in STI screening and diagnosis through image recognition and patient data analysis, potentially increasing diagnostic accuracy while ensuring inclusivity. AI can fuel the transformation of e-health and direct-to-consumer services, enhancing targeted screening and personalized interventions while improving the user-friendliness of services. There is a significant role for AI in sexual education, particularly its use in interactive, empathetic chatbots. AI's integration into health care as a decision support tool for primary health-care providers can boost real-time diagnostic accuracy. Furthermore, AI's use in big data can enhance real-time epidemiology, predictive analysis, and directed interventions at population levels. However, challenges such as real-world diagnostic accuracy, liability, privacy concerns, and ethical dilemmas persist. Future directions include an emphasis on inclusivity, language accommodation, and swift research-to-practice transitions. Collaboration among policymakers, researchers, and health-care providers is needed to leverage AI's transformative potential in sexual health.

Effect of e-health interventions on HIV prevention: a protocol of systematic review and meta-analysis

BACKGROUND

Global epidemiological data indicates that despite implementation of multiple interventions and significant financial investment, the HIV/AIDS epidemic remained inadequately controlled as of 2020. E-health presents a novel approach in delivering health information and health care and has gained popularity in HIV prevention worldwide. However, evidence on the effectiveness of e-health interventions on HIV prevention among diverse populations remains inadequate. Our study aims to systematically evaluate the effectiveness of varying e-health interventions on HIV prevention, with the objective of providing data support and guidance for the development of future e-health HIV intervention strategies.

METHODS

A systematic search of electronic English databases, including MEDLINE through PubMed, Embase, Scopus, and Web of Science, along with three Chinese databases, including National Knowledge Infrastructure (CNKI), Chinese Wanfang Digital Periodicals (WANFANG), and Chinese Science and Technology Periodicals (VIP) database, will be conducted for the period of 1 January 1980 to 31 December 2022. Additionally, gray literature and unpublished trials in trial registers will be searched. Studies aimed at HIV prevention through e-health interventions, with full-text publications available in either English or Chinese, will be included. Study types will be limited to RCT, cluster RCT, and quasi-experiment study. The risk of bias in individual studies will be assessed following the guideline highlighted by the Cochrane Handbook for Systematic Reviews of Interventions. The outcomes will cover cognitive, behavioral, psychological, management, and biological measures of individuals involved in e-health interventions. The quality of evidence will be assessed by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. Ultimately, a systematic review with meta-analysis will be conducted to compare the effectiveness of e-health interventions among diverse populations.

DISCUSSION

This systematic review seeks to establish novel insights into the effectiveness of e-health interventions in diverse populations worldwide. It will inform the design and use of e-health interventions to optimize HIV-related strategies.

Informal sexual relationship-associated factors among young adult smartphone users in South of Iran: a cross-sectional study

BACKGROUND

With the unprecedented pace of modernization, risky sexual behaviors have become more frequent in developing countries, such as Iran. We aimed to assess the prevalence of informal sexual relationship (ISR) and factors associated with having ISR in young adult in Iran.

METHODS

This cross-sectional study was conducted on 414 young adult smartphone users in Iran, in 2019. Data was collected through an online questionnaire (including: ISR, socio-demographic variables, their use of social network, religious beliefs, personality, and loneliness). Logistic regression model was used to determine factors related to ISR.

RESULTS

A total of 152 (36.7%; 95% CI 32.1-45.6) participants reported having ISR. Finding an opposite-sex friend through a mobile app (OR = 2.59, 95% CI 1.34, 5.01), being currently sexually active (OR = 2.39, 95% CI 1.26, 4.56), higher scores of extroverted personality (OR = 1.13, 95% CI 1.01, 1.27), and closer relationship with parents (OR = 3.17, 95% CI 2.25, 8.02) were found to be associated with having ISR. Additionally, living in small cities rather than the provincial capital (OR = 0.23, 95% CI 0.10, 0.49) had a reverse association with having ISR.

CONCLUSIONS

This study illustrated the high prevalence of ISR and its association with increased duration of internet and mobile app use. Innovative and multidisciplinary approaches could be recommended in this regard.

Our relationships, our values, our culture - Aboriginal young men's perspectives about sex, relationships and gender stereotypes in Australia

Studies of Aboriginal young people have often followed a deficit approach depicting them as 'risky' and in need of help. In contrast, this study took a strengths-based approach and focussed on what Aboriginal young people value, how they stay safe and how their culture impacts their lives. 16 Aboriginal men aged 16 to 24 years were interviewed in Sydney, Australia. We examined Aboriginal young men's perspectives about relationships, sex and gender. Interviews were conducted by young Aboriginal men in 2019 and 2020. Overall, four features of positive sexual and romantic relationships were discussed: (1) love, connection and support; (2) enjoyment and fun; (3) responsibility, safety and consent; and 4) honesty, respect and trust. Additionally, three topics related to gender roles: (1) becoming a man; (2) sex as a masculine achievement; and (3) inequality and gender stereotypes. Our study suggests that Aboriginal young men are exploring sexual and romantic relationships, and although they value enjoyment and fun, they are aware of broader issues such as consent and respect. The young men acknowledged gender stereotypes faced by young women. Our results could be used by future school safe sex education programmes to better meet the needs of Aboriginal young men.

Using social and sexual networking mobile applications to promote HIV testing, medical care and prevention services among Latino men who have sex with men in Los Angeles County, California, USA

HIV disproportionately affects Latinos versus Whites, with Latinos having higher rates of HIV. Additionally, many HIV-positive Latinos are unaware of their infection. Proyecto Protégete, an HIV prevention intervention developed for Latino men who have sex with men (MSM), used social and sexual networking mobile applications (apps) to recruit individuals for HIV testing and linkage to medical care and prevention services. This study occurred in Los Angeles County, California, USA from December 18, 2015 to April 22, 2017. The study’s primary aim was to assess Proyecto Protégete‘s ability to successfully recruit Latino MSM involved in high-risk sexual activities. A secondary aim was to evaluate its capacity to promote HIV testing and linkage to HIV medical care and prevention services among this population by comparing it to two programs with similar samples. Comparisons using Fisher’s Exact Test were conducted between Proyecto Protégete and the HIV testing program of the agency in which Proyecto Protégete was located and the County-funded HIV testing programs to compare the samples’ rates of HIV-positive Latino MSM identified through HIV testing and linked to HIV medical care and prevention services. Participants were recruited through seven apps. In Proyecto Protégete, 9,573 individuals completed the screener, 4,657 were eligible, and 359 (7.7% of those eligible) enrolled. Among those enrolled, 79% reported anal sex without a condom in the previous twelve months; 51% reported anal sex under the influence of alcohol. The HIV positivity rates were as follows: Proyecto Protégete, 1.71%; the agency, 1.25% (p = .293, compared to Proyecto Protégete); and the County, 1.09% (p = .172, compared to Proyecto Protégete). The rates of those confirmed as new HIV-positives and linked to medical care within 30 days were as follows: Proyecto Protégete, 71.4%; the agency, 81.5% (p = .450, compared to Proyecto Protégete); and the County, 77.3% (p = .503, compared to Proyecto Protégete). Proyecto Protégete had a higher rate of linked referrals to prevention services than the agency’s testing program (19.5% versus 8.3%, p < .001). Proyecto Protégete experienced successes in some areas but not in others. Future research should build on Proyecto Protégete’s experiences to promote HIV-related services among Latino MSM.

Traversing TechSex: benefits and risks in digitally mediated sex and relationships

BACKGROUND

Digital technologies play a significant role in people's sexual and intimate lives via smart phones, cameras, dating apps and social media. Although there is a large body of research on the potential risks posed by these technologies, research on benefits and pleasures is limited.

METHODS

This study explored digital sexual practices, including perceptions of risks and benefits among a sample of Australian adults (n=445). Data were collected in 2020 via an online survey. Descriptive and bivariate analyses were undertaken to identify significant relationships between demographic variables and the use of technologies in relation to perceived risks and benefits. The mean age of participants was 42 years, over half were women (58.5%) and identified as heterosexual (61.1%).

RESULTS

Findings reveal that use of digital media was common in participants' sex lives and relationships; 60.3% of participants had viewed pornography online, 34.9% had used dating apps, and 33.9% had sent sexual or naked self-images to another person. Over one in three reported positive outcomes from this: 38.2% felt emotionally connected to their partners due to online communication; 38.0% agreed that digital technologies facilitated closer connections;however, the majority of participants were aware of potential risks associated with online sexual engagement, particularly non-consensual exposure of their sexual or naked images, with women expressing greater concern.

CONCLUSIONS

Policy, legal and educational responses should be based on holistic understanding of digital sexual engagement, acknowledging the ways in which technologies can support sexual relationships while also building people's knowledge and capacity to manage risks.

Lights, camera…research! Short film and social media to recruit to HIV research in Indonesia

Introduction

HIV prevalence among men who have sex with men has increased in Indonesia, amid reports of growing stigma against lesbian, gay, bisexual and transgender individuals and policies that have pushed back public health outreach to these groups.

Methods

We assessed the utility of tailored short film and targeted social media engagement to recruit men who have sex with men in Indonesia to HIV social science research. A short HIV testing promotion film, anonymised short survey and invite to a wider research study was embedded on a website platform and disseminated using geo and social/community group targeting for 1 month via a social networking app and social media platforms.

Results

From 3 January 2021 to 3 February 2021, there were over 2200 hits of the website within Indonesia. A total of 177 male web users who identified as men who have sex with men or preferred not to declare their sexuality, engaged by watching the short film and completing the survey, they were aged between 17 and 60 years old, of Indonesian nationality and living in Indonesia. Of these, 88% indicated having at least one HIV test in their lifetime, 66% had felt shame with respect to their sexuality and 53% indicated feeling afraid to have a HIV test. Ninety (51%) of the 177 validated using their email or mobile phone number demonstrating willingness to be contacted to join a further study. Twenty-three eligible men who have sex with men, aged 21–55 years old, joined a further social science research study. Participants were from diverse backgrounds and included men born in provinces outside Bali, of different socio-economic and employment backgrounds and diverse relationship contexts.

Discussion

Engaging, empowering digital media involving key health messaging can provide health education in more effective ways, build trust and bring communities together. Targeted digital and social media approaches could reach increasingly marginalised and vulnerable communities to promote individual and public health and enable recruitment to valuable medical research.

Gender Differences in How Parents, Peers, and Exposure to Sexually Explicit Materials Influence the Intention to Engage in Casual Sex among Adolescents and Young Adults in Taiwan: Applying the Theory of Planned Behavior

The aims of this study were to examine gender differences in how parent-child discussions on sex issues, peer interactions around sexual issues, and exposure to sexually explicit materials affect the intention to engage in casual sex among adolescents and young adults in Taiwan. This cross-sectional survey study recruited 767 participants (348 men and 419 women) aged 15-24 years. The survey collected data on participants' intention to engage in casual sex, their attitude toward and perception of casual sex based on the theory of planned behavior (TPB) (favorable attitude, perceiving positive social norms toward casual sex, and perceived control over involvement), parent-child and peer discussions about sexual issues, and exposure to sexually explicit materials. The results of multiple regression analysis revealed that parent-child discussions on sex issues, peer interactions around sexual issues, and exposure to sexually explicit materials were significantly associated with the intention to engage in casual sex. The results of structural equation modeling (SEM) further supported that favorable attitude, perceiving positive social norms toward casual sex, and control over involvement mediated the associations. For men, decreased favorable attitude mediated the negative association between parent-child discussions and casual sex intention; increased favorable attitudes and decreased control over involvement mediated the positive associations between peer interactions and casual sex intention. For women, decreased control over involvement mediated the positive association between exposure to sexually explicit materials and casual sex intention. The associations between peer interaction and subjective norms of acceptance, perceived control over involvement, and casual sex intention were stronger in men than in women; the association of favorable attitudes with casual sex intention was also stronger in men than in women.

Associations Between Methods of Meeting Sexual Partners and Sexual Practices Among Heterosexuals: Cross-sectional Study in Melbourne, Australia

Background

The association between meeting partners on the web and sexual practices has been understudied in heterosexuals.

Objective

This study aims to examine the associations between the methods of meeting partners and sexual practices and HIV and sexually transmitted infections (STIs) in heterosexuals.

Methods

We conducted a survey among heterosexuals attending the Melbourne Sexual Health Centre in 2019. This survey asked about the methods through which the participants engaged in meeting their sexual partners, sexual practices, and intravenous drug use (IVDU) over the past 3 months. The participants’ HIV and STI (chlamydia, gonorrhea, and syphilis) status was obtained from clinical testing. Multivariable logistic regression was used to examine the association between each method of meeting and the participants’ sexual practices, IVDU, and STI status.

Results

A total of 698 participants (325 men and 373 women) were included in the study. Most of the participants reported using only one method to meet partners (222/325, 68.3% men; 245/373, 65.7% women; P=.05). The men met partners most commonly at social venues (eg, bar, pub, or party; 126/325, 38.8%), whereas the women met partners most commonly through friends or family (178/373, 47.7%). Paying for sex was associated with men meeting partners at sex venues (adjusted odds ratio [AOR] 145.34, 95% CI 26.13-808.51) and on the internet (AOR 10.00, 95% CI 3.61-27.55). There was no association between IVDU and methods of meeting. Social venues were associated with condomless vaginal sex among men (AOR 3.31, 95% CI 1.94-5.71) and women (AOR 2.58, 95% CI 1.61-4.13) and testing positive for STI among men (AOR 3.04, 95% CI 1.24-7.48) and women (AOR 3.75, 95% CI 1.58-8.89).

Conclusions

Heterosexuals who met partners at social venues had a more than threefold risk of testing positive for STIs, indicating that heterosexuals may benefit from health promotion campaigns that are delivered through a public setting.

Motivations, dating app relationships, unintended consequences and change in sexual behaviour in dating app users at an Australian music festival

BACKGROUND

Despite the popularity of dating apps, there remain scarce data on the motivations, consequences and their influence on sexual behaviour change in the Australian population.

OBJECTIVE

To explore motivations, dating app relationships, unintended consequences and change in sexual behaviour in dating app users at an Australian music festival.

METHODS

A cross-sectional study design was used. Festival patrons aged 18-30 at a major Australian music festival completed a paper-based survey. Logistic regression was used to identify which factors were associated with an increase in sexual partners since using dating apps.

RESULTS

The primary reasons for dating app use (N = 437) were boredom (59.7%), casual sex (45.1%) and casual dating (42.8%). A third of users used them at music festivals (33.8%, n = 432). A third of participants had used dating apps for more than 2 years (33.3%) and a third (33.0%) of users claimed to have changed their sexual behaviour after app use, including increased frequency of sexual activity (70.0%), number of sexual partners (57.1%) and sexual experimentation (42.1%). Dating app users tended not to discuss sexually transmitted infections (STI) status with a sexual partner regardless of whether they had met them on an app or not: 38.5% would 'never' and 36.9% would 'sometimes' have safe sex discussions with partners met via apps. Condoms were 'always' used for 36.9% of dating app users when meeting partners via dating apps, compared to 29.9% met by other means. 8.6% of dating app users reported having contracted STIs, and 2.8% had unwanted pregnancies with those met on dating apps. After adjusting for socio-demographics, those who had an STI after engaging in sexual activity with a person met via a dating app had 2.4 times the odds of reporting an increase in sexual partners, and those who had used a dating app for over 2 years had twice the odds of reporting an increase in sexual partners. When condom use was entered into the model, those that 'often' or 'sometimes' used a condom with a new dating app partner were twice as likely to report an increase in sexual partners since using dating apps, compared to those who 'always' used a condom with a new dating app partner. Sexual orientation and STI discussions with a new sexual dating app partner were not associated with an increase in dating app partners.

CONCLUSION

Dating app usage is common and users report increased sexual activity, sexual partners and experimentation. STI discussions with potential partners and condom use remained low regardless of how partners were met and despite an increase in sexual partners since using dating apps. Given the high-risk nature of individuals that utilise dating apps, safe sex discussion, including STIs, pregnancies and condom use should be promoted to improve sexual health outcomes.

A digital health research platform for community engagement, recruitment, and retention of sexual and gender minority adults in a national longitudinal cohort study--The PRIDE Study

OBJECTIVE

Sexual and gender minority (SGM) people are underrepresented in research. We sought to create a digital research platform to engage, recruit, and retain SGM people in a national, longitudinal, dynamic, cohort study (The PRIDE Study) of SGM health.

MATERIALS AND METHODS

We partnered with design and development firms and engaged SGM community members to build a secure, cloud-based, containerized, microservices-based, feature-rich, research platform. We created PRIDEnet, a national network of individuals and organizations that actively engaged SGM communities in all stages of health research. The PRIDE Study participants were recruited via in-person outreach, communications to PRIDEnet constituents, social media advertising, and word-of-mouth. Participants completed surveys to report demographic as well as physical, mental, and social health data.

RESULTS

We built a secure digital research platform with engaging functionality that engaged SGM people and recruited and retained 13 731 diverse individuals in 2 years. A sizeable sample of 3813 gender minority people (32.8% of cohort) were recruited despite representing only approximately 0.6% of the population. Participants engaged with the platform and completed comprehensive annual surveys- including questions about sensitive and stigmatizing topics- to create a data resource and join a cohort for ongoing SGM health research.

DISCUSSION

With an appealing digital platform, recruitment and engagement in online-only longitudinal cohort studies are possible. Participant engagement with meaningful, bidirectional relationships creates stakeholders and enables study cocreation. Research about effective tactics to engage, recruit, and maintain active participation from all communities is needed.

CONCLUSION

This digital research platform successfully recruited and engaged diverse SGM participants in The PRIDE Study. A similar approach may be successful in partnership with other underrepresented and vulnerable populations.

Do we need to worry about sexually transmissible infections (STIs) in older women in Australia? An investigation of STI trends between 2000 and 2018

Background This study examined trends in chlamydia, gonorrhoea and syphilis diagnosis, and chlamydia testing and positivity, among older women in Australia between 2000 and 2018.

METHODS

Using national notifiable disease data and Medicare data, diagnosis rates were calculated for each sexually transmissible infection (STI), as well as testing and positivity rates for chlamydia. Data were compared between two older groups (55-64 and 65-74 years) and two younger groups (15-24 and 25-34 years). Poisson regression examined trends for 2000-18 and 2014-18 separately.

RESULTS

Rates for all STIs increased across all age groups and were highest in the two youngest age groups. From 2014 to 2018, chlamydia rates increased the most among those aged 55-64 years [incidence rate ratio (IRR) = 1.06; 95%CI: 1.02-1.10] and declined in those aged 15-24 years (IRR = 0.99; 95%CI: 0.99-0.99). Gonorrhoea rates increased the most among those aged 65-74 years (IRR = 1.47; 95%CI: 1.23-1.77) and least in those aged 15-24 years (IRR = 1.12; 95%CI: 1.10-1.13). Syphilis rates increased the most among those aged 55-64 years (IRR = 1.58; 95%CI: 1.25-1.99) and least in those aged 15-24 years (IRR = 1.29; 95%CI: 1.23-1.35). Chlamydia test positivity declined among younger women but remained stable in older women.

CONCLUSIONS

In general, STIs are increasing among older women in Australia at a faster rate than among younger women. Although the greatest burden is among younger women, STIs need to be considered and monitored among older women.

Getting Indonesia's HIV epidemic to zero? One size does not fit all

Indonesia has one of the fastest growing HIV epidemics in the world. AIDS related deaths in Indonesia have not fallen and have increased significantly since 2010. HIV infection rates remain high and rising in key affected populations. We provide an on the ground, evidence-based perspective of the challenges Indonesia faces. We discuss what is required to adopt tailored public health approaches that address context specific challenges, confront structural barriers and the heterogeneity of the current evolving HIV epidemic.

Use of dating sites and applications by women and their risk of sexually transmitted infections: a systematic review and meta-analysis protocol

INTRODUCTION

The use of social networks has been increasing worldwide. Mobile websites and applications (apps) allow people to network more quickly and have more partners for sex. This can facilitate risky sexual behaviours, such as having multiple partners and unprotected sex, which can lead to a higher incidence of sexually transmitted infections. This systematic review/meta-analysis will assess the effects of the use of dating sites and apps by women on their level of engagement in risky sexual behaviours and their incidence of sexually transmitted infections.

METHODS AND ANALYSIS

The Cochrane Central Controlled Trials Registry, ClinicalTrials.gov, MEDLINE, Embase, SciELO, Web of Science, Scopus and Cumulative Index to Nursing & Allied Health Literature will be searched for cross-sectional studies, clinical trials and observational studies published between January 1990 and July 2020. This systematic review and meta-analysis will include studies investigating the use of mobile apps by women, risky sexual behaviour and sexually transmitted infections. The outcome will be an increase in new cases of sexually transmitted infections and HIV among women using dating sites and apps. Three independent reviewers will select the studies and extract data from the original articles. The risk of bias will be assessed using the Cochrane risk of bias tool and Risk Of Bias in Non-randomized Studies of Interventions. Data synthesis will be performed using Review Manager software (RevMan V.5.2.3). To assess heterogeneity, we will compute the I2 statistic. In addition, a quantitative synthesis will be carried out if the included studies are sufficiently homogeneous.

ETHICS AND DISSEMINATION

This study will be a review of the published data, and thus ethical approval is not required. The findings of this systematic review will be published in a peer-reviewed journal.

Mobile App Strategy to Facilitate Human Papillomavirus Vaccination Among Young Men Who Have Sex With Men: Pilot Intervention Study

Background

Mobile app-based interventions have been identified as potential facilitators for vaccination among young men who have sex with men (MSM).

Objective

This pilot study aimed to test the feasibility of a theoretically informed mobile health (mHealth) tool designed to reduce health disparities and facilitate human papillomavirus (HPV) vaccination among a sample of young MSM.

Methods

The development of the mHealth tool was guided by previous research, implementation intention theory, and design thinking. We recruited MSM aged 18-26 years through a popular online dating app and linked participants to our mHealth tool, which provided HPV vaccine information and fostered access to care.

Results

A total of 42 young MSM participated in this pilot study in Boston, Massachusetts. Participants reported variable HPV knowledge (ie, high knowledge of HPV risk factors and low knowledge of HPV-related cancer risks for men) and positive vaccine beliefs and attitudes. Of those who were either unvaccinated, not up to date, or did not report vaccine status, 23% (8/35) utilized the mHealth tool to obtain HPV vaccination. Participants primarily utilized the tool’s (1) educational components and (2) capabilities facilitating concrete vaccine action plans.

Conclusions

We recruited an underserved at-risk population of youth via an online dating app for our mHealth intervention that resulted in in-person health care delivery. This study was limited by enrollment challenges, including low willingness to download the mHealth tool to mobile devices.

Epidemiology of gonorrhoea: a global perspective

Although understanding the local epidemiology of gonorrhoea is critical for local efforts, understanding the multinational epidemiology may support development of national and international prevention and control policies and strategies. In this paper, current epidemiology of gonorrhoea is reviewed through an international lens and with a focus on selected populations. The World Health Organization (WHO) estimates that ~87 million new gonococcal infections occurred among people aged 15-49 years in 2016. Gonorrhoea rates are rising in many countries. Gay, bisexual and other men who have sex with men, racial or ethnic minorities, Indigenous populations and sex workers appear to bear disproportionate burdens of gonorrhoea. International travel can facilitate spread of gonorrhoea, including resistant strains, across international borders. Critical gaps in epidemiological knowledge are highlighted, including data on gonorrhoea among transgender persons and the burden of extragenital gonorrhoea. Even as further data are gathered, action - informed by currently available data - is needed now to confront this growing international threat.

Associations Between Affective States and Sexual and Health Status Among Men Who Have Sex With Men in China: Exploratory Study Using Social Media Data

Background

Affective states, including sentiment and emotion, are critical determinants of health. However, few studies among men who have sex with men (MSM) have examined sentiment and emotion specifically using real-time social media technologies. Moreover, the explorations on their associations with sexual and health status among MSM are limited.

Objective

This study aimed to understand and examine the associations of affective states with sexual behaviors and health status among MSM using public data from the Blued (Blued International Inc) app.

Methods

A total of 843,745 public postings of 377,610 MSM users located in Guangdong were saved from the Blued app by automatic screen capture. Positive affect, negative affect, sexual behaviors, and health status were measured using the Simplified Chinese Linguistic Inquiry and Word Count. Emotions, including joy, sadness, anger, fear, and disgust, were measured using the Weibo Basic Mood Lexicon. A positive sentiment score and a positive emotion score were also calculated. Univariate and multivariate linear regression models on the basis of a permutation test were used to assess the associations of affective states with sexual behaviors and health status.

Results

A total of 5871 active MSM users and their 477,374 postings were finally selected. Both positive affect and positive emotions (eg, joy) peaked between 7 AM and 9 AM. Negative affect and negative emotions (eg, sadness and disgust) peaked between 2 AM and 4 AM. During that time, 25.1% (97/387) of negative postings were related to health and 13.4% (52/387) of negative postings were related to seeking social support. A multivariate analysis showed that the MSM who were more likely to post sexual behaviors were more likely to express positive affect (beta=0.3107; P<.001) and positive emotions (joy: beta=0.027; P<.001), as well as negative emotions (sadness: beta=0.0443; P<.001 and disgust: beta=0.0256; P<.001). They also had a higher positive sentiment score (beta=0.2947; P<.001) and a higher positive emotion score (beta=0.1612; P<.001). The MSM who were more likely to post their health status were more likely to express negative affect (beta=0.8088; P<.001) and negative emotions, including sadness (beta=0.0705; P<.001), anger (beta=0.0058; P<.001), fear (beta=0.0052; P<.001), and disgust (beta=0.3065; P<.001), and less likely to express positive affect (beta=−0.0224; P=.02). In addition, they had a lower positive sentiment score (beta=−0.8306; P<.001) and a lower positive emotion score (beta=−0.3743; P<.001).

Conclusions

The MSM social media community mainly expressed their positive affect in the early morning and negative affect after midnight. Positive affective states were associated with being sexually active, whereas negative affective states were associated with health problems, mostly about mental health. Our finding suggests the potential to deliver different health-related intervention strategies (eg, psychological counseling and safe sex promotion) on a social media app according to the affective states of MSM in real time.

Development and Testing of a Mobile Phone App for Risk Estimation of Gas Volume Expansion and Intraocular Pressure Elevation in Patients With Intravitreous Gas or Air Tamponade: Interobserver Assessment Study

Background

Pars plana vitrectomy (PPV) with intravitreous tamponade of gas or air has been widely used for a series of vitreoretinal diseases. It is estimated that 100,000 patients per year undergo PPV globally, and half of them were subsequently tamponaded with gas or air. According to Boyle’s law (P₁V₁=P₂V₂), patients with an intravitreous remnant of gas or air will be under high risk of intraocular pressure (IOP) elevation and subsequent vision loss owing to the expanded intravitreous gas or air when traveling post operation to a place with a significantly higher altitude. We always explain to patients why postoperative travel is potentially risky. Emergency cases of elevated IOP caused by postoperative traveling would sometimes come to surgeons. However, there have been few disease education or reference tools for both the surgeons and patients to have better communication.

Objective

The aim of this study was to introduce and evaluate a mobile phone app developed by surgeons (the authors) for preliminary risk estimation of volume expansion and IOP elevation in patients with intravitreous gas or air when traveling to a place of higher altitude.

Methods

The app was developed on the iOS and Android operating systems. Boyle’s law (P₁V₁=P₂V₂) was the theoretical basis of the app. Intravitreous gas or air volume and altitude values were independent factors to deduce the risk report. Consecutive patients underwent vitrectomy, and those with an intravitreous remnant of gas or air were recruited. The surgeons judged the vertical height of the fluid/gas interface through the dilated pupil; the patients were instructed to judge it according to their visual field when looking straight ahead and line it out on a chart included in the app. Finally, all the patients were required to fill a Likert scale–based questionnaire with 2 main items to evaluate the participants’ user experience and attitudes toward the app.

Results

A total of 50 patients were included (30 males and 20 females). All patients could independently operate the app to complete the test. The median heights of the fluid/gas interface independently judged by the surgeon and patients were 40% (range: 10%-75%) and 41% (range: 9%-78%), respectively (P=.63). The median altitude of the participants’ destinations was 150.0 m (range: 0-3490 m). The Bland-Altman analysis revealed a good agreement between the surgeons’ and patients’ judgments (bias of −0.3%), with 95% limits of agreement of −5.8% to 5.3%. Overall, the Likert scale revealed a positive attitude from the patients toward the app.

Conclusions

The app is reliable for patients to have preliminary risk estimation of intravitreous gas or air volume expansion and IOP elevation if travel to a place of higher altitude is planned. The surgeons could also use it as a platform for better disease communication.
